重庆南温泉背斜地下热水资源衰减过程数值模拟研究

在论述重庆南温泉背斜地下热水的水文地质特征的基础之上,采用有限元数值模拟方法,建立数学模型;并采用实测水位与模拟水位对比进行模型校正,当模拟水位与实测水位相近时,所得的模型是符合客观实际的.根据南温泉地下热水水位下降的特征,分4个阶段,采用已校正的数学模型模拟分析1962年到1991年南温泉地下热水资源量衰减的过程,定量分析其衰减原因.南温泉背斜地下热水水位降低,天然温泉断流,原因为同一个地下热水系统被多个开发点混乱开采.此研究为今后合理开发和有效保护地下热水资源环境提供科学依据.

Numerical simulation of the hot water resource attenuation process in the Nanwenquan anticline of Chongqing,China

The paper discussed the hydro-geological conditions. The geological mode was generalized and the mathematical model was established. Then, the simulative water level was compared with actual one, and then the mathematical model was identified and adjusted. The right mathematical model had been acquired when the simulative water level is approximate to actual water level. The infiltration of hot water was simulated about its level from 1962 to 1991; the time had disparted to 4 phase that basis on the variety characteristic of water level. The causation of hot water resource attenuation had analyzed. It result show the causation is each does things in his own way and had not plan exploitation on every exploitation point in a hot water system. The research provides foundation for the hot water resources scientific management and rational exploitation.
